• Generators and transmission motors

We would like to introduce a case study of the gas turbine generator we manufactured. We were responsible for the design and production of a generator specifically for this gas turbine, with a speed of 80,000 rpm and an output of 40 kW. We applied the technology of Halbach array magnetic field rotating machines for this specialized design. This generator is also utilized as a starter motor for the gas turbine, rotating from a standstill to an idling speed of 40,000 rpm using an inverter, thereby assisting in the combustion of the gas turbine. 【Case Overview】 ■ Equipment: Gas turbine generator ■ Specifications: 80,000 rpm, 40 kW output *For more details, please download the PDF or feel free to contact us.

• DC Motor

We handle the "Halbach NR Motor," which is a motor that utilizes the Halbach array formed by rotating the magnetization direction of permanent magnets. Our design leverages the characteristics of the Halbach array, allowing for configurations such as high-speed rotation, low torque ripple, and high efficiency. Additionally, the shape of the yoke and coils is a key point, and we design with various phenomena in mind, such as mirror image effects and proximity effects, to suppress losses and vibrations. 【Features】 - Low-loss design that reduces the amount of iron used compared to IPMSM - Smooth operation even at low speeds due to being a coreless motor - Accommodates various requests regarding voltage, rotation speed, materials, weight, cooling methods, etc. - Compatible with built-in types - Offers proposals and support for drive inverters *For more details, please download the PDF or feel free to contact us.
